Method of identification and limitation of the basic reasons which form the sculpture of the tread of a tyre.Method for inspection of the tread of a tyre of which the sculpture is formed by the union of the elements juxtaposed ring, separated from each other by borders forms are identical and have basic reasons, few sequenced accurately we known.Which include at least one reason basis on which are willing to wear indicators which is associated with a characteristic point of the basic motive, in which: is held an image of the tread of the tyre, inspecting, are identified the tread wear indicators pre Feeling in the image of the tread of the tyre to inspect.The tread wear indicators are grouped together and is determined by the characteristic point of each of these subsets, is given a sequence of distances is calculated so that the distances between the characteristic points of each of the subsets of wear indicators identified S on the surface of the tread to inspect.This sequence of distances is made coincide with the known sequence of the distances between the characteristic points of the basic reasons, is projected on the surface to inspect the shape of the boundary between the elements according to the sequence known for positioning said The elements.
